Today we had the third meeting of the DEMA project at the INRIA center of Grenoble/Minatec.
I presented the work done so far on the interactive profiling and debugging of sequential applications.
Today we had our end-of-year meeting of the DEMA project between the mountains of Chamonix.
I presented the work done so far on the integration of OpenMP 4.0 into mcGDB. It was focused on task debugging, with a cooperation with Temanejo debugger.
Today I presented my work at the JLESC workshop at Bonn, Germany. It was a 20’ presentation entitled:
Programming-Model Centric Debugging for OpenMP/OMPss
Today I gave a 45’ seminar talk at the HLRS center of Stuttgart, Germany, about my thesis work.
The goal of the meeting was to discuss the cooperation between Temanjo and mcGDB, which was successfully implemented in the following months (see D3 deliverable of DEMA).
Today we had the first meeting of the DEMA project at the University Paris VI.
I presented the work done so far on the integration of OpenMP 3.0 into mcGDB. It was focused on two aspects:
Representing and Controlling Fork-Join Applications
Execution Representation with Sequence Diagrams
As part of the Montblanc project, I work on the porting of SPECFEM 3D Globe from OpenCL to CUDA. Then I performed an in-depth study of its performance on the energy-efficient Montblanc cluster. SPECFEM3D Globe is an HPC scientific code that simulates seismic wave propagation at the local or regional scale based upon spectral-element method (SEM) with very good accuracy and convergence properties.
The OpenCL port was merged in the upstream git:
The performance study was published as a public deliverable of the project:
For the benchmarking, SPECFEM3D was configured to simulate a regional-scale Greek earthquake. It ran over one or two cores, with or without GPU acceleration, on 128 ARM nodes.
We studied the weak and strong scaling, as well as the energy consumption profile of the cluster.
Today we’ve officially started the DEMA project, part of the Nano2017 national program. DEMA is focused on OpenMP functional and interactive debugging. It stands for
Debugging Embedded Multicore Applications
Last week I presented my thesis work at the 2nd workshop on Multicore Application Debugging workshop. It was entitled:
Programming-Model Centric Debugging for Multicore Embedded Systems
